Merge tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging

Pull hwmon fixes from Guenter Roeck:
 - Fix a resource leak in tmp103 driver
 - Add support for two more processors to fam15h_power driver
 - Also fix a bug in the same driver to only report the power level on
   chips which actually support reporting it

* tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging:
  hwmon: (tmp103) Fix resource leak bug in tmp103 temperature sensor driver
  hwmon: (fam15h_power) Add support for two more processors
  hwmon: (fam15h_power) Make actual power reporting conditional
